Please use the code tags and indent your code.

 

Within your function, $select is not defined. You probably want to just create it the first time, rather than trying to append to it.

$select = "<select...

rather than

$select .= "<select...

[stutego]

@Jessica please i've tried it out, but only got just the (contine) button please help me out my still a newbie to php

[Jessica]

Post your updated code. In code tags. Use the plain text editor if you need to.

If you changed it EVERYWHERE and not just the first time you try to use that variable, that won't work. Think about it.

[Barand]

Your function needs to

 

return $select;

[stutego]

the updated code took off the error but wasnt giving me the dropdown list i coded

this is the updated code

<?php
//lets select options from a dropdown list using php functions
$month = array("jan" => "Jan", "feb" => "Feb", "mar" => "Mar", "apr" => "Apr", "may" => "May", "jun" => "Jun", "jul" => "Jul", "aug" => "Aug", "sep" => "Sep", "oct" => "Oct", "nov" => "Nov", "dec" => "Dec");
		 $default = "jan";
$select = generate_menu("month", $month, $default);
function generate_menu($name, $month, $default="") {
$select= "<SELECT NAME=\"$name\">";
foreach($month as $value => $label) {
$select= "<OPTION ";
if ($value == $default)
$select= "SELECTED ";
$select= "VALUE=\"$value\">$label</OPTION>";
}
$select= "</SELECT>";
return($select);
}
?>
<FORM ACTION="month.php" METHOD=POST>
<?php print $select;?>
<INPUT TYPE=SUBMIT VALUE="Continue">

Using the advice that Jesi initially gave you, and with a little cleanup added, this code should work for you:

 

$month = array("jan" => "Jan", "feb" => "Feb", "mar" => "Mar", "apr" => "Apr", "may" => "May", "jun" => "Jun", "jul" => "Jul", "aug" => "Aug", "sep" => "Sep", "oct" => "Oct", "nov" => "Nov", "dec" => "Dec");
$default = "jan";
$menu = generate_menu("month", $month, $default);
function generate_menu($name, $month, $default="")
{
$select = "<select name='$name'>";
foreach($month as $value => $label)
{
$select .= "<option ";
if ($value == $default)
$select .= "selected='selected' ";
$select .= "value='$value'>$label</option>";
}
$select .= "</select>";
return $select;
}
echo $menu;

 

Also, the function returned $select from the initial post.

Your function needs to

 

return $select;

 

return $select; is there

You did like maybe 1/5th of what this post says.

much tanx to Jessica, Aykay47 & Barand 4 helping me out with my prob i used Aykay47's anwser and it worked out well....

what did u mean by saying i did just 1/5th and can u explain the remaining 1ce i did'nt do

[Jessica]

You didn't post using the code tags. You apparently didn't read the entire second sentence, because it explains what's wrong with your code. I'm guessing you don't understand what .= and = do.

haha i forgot adding the tag

tanx a lot Jessy wil love u helping out next time on any prob

[stutego]

but please @jessy what are diff btw .= & = and what are their functions to the code

[Jessica]

Hey stupido. Look it up in the manual. Give it like, 5 minutes of your own time and try to learn it.

 

Also this isn't twitter, and my name is Jessica.

[stutego]

k m sorry @Jessica but dat ws'nt inclusive in the ebook am using, am using oreilly's php ebook

[KevinM1]

Like Jessica stated, this forum isn't like Twitter. Writing in shortened internet lingo only makes it harder for us to understand what you're saying, which ultimately makes it harder for us to help you. We don't have a 140 character limit, so slow down, write complete sentences, and be as clear and concise as you can about your problem.

 

When posting code, place it within

tags. That will format it and apply syntax highlighting so we can more easily see what's going on.

 

In short, the easier it is for us to understand you and your problem, the faster it will be addressed.

As for what Jess said on like the first or second post she did - about the indenting - when you copy and paste code into the text editor, the text editior takes out all of the indenting thereby making it all just a plain list.

Not if you use the plain text editor. 

function test(){
echo 'hello world';
}

 

I c&p that from my text editor into the plain text here.

[stutego]

ok kelvin tanx 4 that...

[stutego]

tanx to you all for helping out

[woot]

but please @jessy what are diff btw .= & = and what are their functions to the code

 

You may have figured it out by now but replying to your question '=' means you're assigning a value to a variable. For example:

 $a = 5; //means your variable $a receives the value 5

When you use '.=' it will append a string to the value already contained in the variable like

$a = "This is the first sentence."; $a .= " This is the second sentence.";

After this your variable $a will contain the string "This is the first sentence. This is the second sentence.".

 

I hope it's clear enough for you to understand.

[AyKay47]

stutego, this link will help you understand the concept of concatenation better.
